Please feel free to pass this information along to any interested students.
Applicants can contact me directly at jdodd at niu.edu.

The Department of Geology and Environmental Geosciences at Northern
Illinois University has an opening for a graduate research assistantship
starting August 2014. This position is fully funded for 2 years.

The graduate student (MS or PhD) will be conducting research on silicon
isotope variations in diatom frustules and other biogenic silica. Specific
research projects include: 1) developing new techniques for conducting
simultaneous silicon (δ30Si) and oxygen (δ18O) isotope analyses of biogenic
silica on an isotope ratio mass spectrometer (Thermo Scientific MAT 253)
using laser fluorination, 2) conducting laboratory experiments to constrain
changes in δ18O and δ30Si values during growth and diagenesis in different
types of biogenic silica, and 3) constructing a record of silicon isotope
variations in biogenic silica from a previously collected Antarctic marine
sediment core to examine the linkages between silicic acid utilization and
silicon/carbon cycle relationships.
